NOTE:
1.
If the device generating the Interrupt has an open-drain output structure or
can be tri-stated, a pull-up resistor is required.
If the device generating the Interrupt has a totem-pole output structure and
cannot be tri-stated, a pull-up resistor is not required.
The Interrupt inputs should not be left floating.
